Hey there!
• The like terms are already combined! Both of your numbers have “q” in it so they are like terms
• If you had something like this: 4q^2 + 9q^3 they won’t be like terms because they are different
Anyways!
4q + 9q = 4 + 9
⬆️ ⬆️
13q = 13
Thus your answer is would most likely be: 13q
Good luck on your assignment and enjoy your day!
